This Sunday (June 27) Paul McCartney takes to the stage to headline Hard Rock Calling in Hyde Park and YouTube will be hosting a stream from the event at the BornHIVFree channel.

Starting at 8.30pm in the UK (12.30pm Pacific Time), visitors to the channel can enjoy an exclusive broadcast of McCartney's performance, donated by the former Beatle to The Global Fund’s Born HIV Free campaign, which has another high-profile patron in the form of France’s First Lady, Carla Bruni-Sarkozy.

Born HIV Free is urging people pledge their support to The Global Fund’s efforts to eliminate mother to child transmission of HIV by 2015 by adding their names to the organisation’s Support Wall. At present, 45% of HIV-Positive pregnant women have access to the drugs they need to block transfer of the virus to their babies, with Global Fund-supported programmes reaching 790,000 to date… 340,000 in 2009 alone. The goal is clear and your voice could make the difference.

So, as you are listening to Paul McCartney work his way through what – with The Beatles, Wings and his solo recordings – must rank as one of the best sets of songs of all time, spare a minute to find out more about Born HIV Free, The Global Fund and maybe even add your support. YouTube will be updating live on Twitter this Sunday via @youtube, and you can add your comments to a planned Twitter stream on the channel using #bornhivfree.

As pop stars go, Kylie Minogue has proved herself to be one of the most enduring and interesting of the past 20 years. Which is why UK Music Tuesday is happy to announce that she is inviting the YouTube community to put their questions to her via Google Moderator at her channel -- after all, she has a lot to talk about.

When she first hit the charts with “The Locomotion”, it would have taken a brave soul to predict Kylie’s subsequent career arc. Going from Stock, Aitken and Waterman to then of-the-moment (and recently revived) dance label Deconstruction to becoming arguably the hippest female pop act of the 21st century (pre-Lady Gaga) with the incontrovertible video classic “Spinning Around”, featuring ‘those’ gold lame hotpants, you have to say that she has been nothing if not predictable. If you then take into account duets with the likes of Nick Cave and Robbie Williams, suddenly the true measure of her versatility emerges.

Now, with her 11th studio album “Aphrodite”, Kylie shows that she has lost none of her innate allure with the pheromone-packed “All The Lovers” and presumably much, much more to come. Which is where you have a part to play: UK Music Tuesday urges you to head to her channel and put your questions for Kylie Minogue on record using the Google Moderator gadget you'll find on the page. The Top 10 –- as voted for by the YouTube community -- will be put to the former “Neighbours” starlet next month, at which point we’ll reveal all in an exclusive interview on the YouTube UK homepage.

Video editing usually requires installing software packages and having a fair amount of technical savvy. But we think video editing should be fun and easy, so we’re introducing a new tool that anyone -- even this guy -- could figure out: it’s an online video editor, now available in TestTube, our ideas incubator.

Without installing any software, it allows you to:

Combine multiple videos you’ve uploaded to create a new longer video

Trim the beginning and/or ending of your videos

Add soundtracks from our AudioSwap library of tens of thousands of songs

Create new videos without worrying about file formats and publish them to YouTube with one click -- no upload necessary

Watch this video from powerposter rewboss to get a sense of how it works:

See? Pretty easy. The editor is ideal for merging single, short clips into a longer video. For example, you can transform clips from your vacation into a video travel diary set to music, or create a highlights reel from footage of your last football game.

It’s also great for trimming a long video down to the moments you really care about. Say you’ve uploaded a wedding ceremony -- beautiful event, but do you really need to see all the guests shuffle in? The video editor lets you easily remove unwanted footage so you can capture just the moment when they say “I do.”

Please play with it and let us know what you think in the comments below and/or check out more info about it in our Help Centre. We’re looking forward to adding new features based on your feedback to make the video editor more powerful while still retaining its simplicity.

Do you ever look at a YouTube video and think, "That's a work of art?" Yep, so do we -- and now, so does the Guggenheim.

In five years, YouTube has redefined media culture by changing the way the world creates, distributes and watches video. Online video is exploding not just as a medium, but as an art form, and we're proud of the originality and innovation that YouTube has fostered among our users. Our community has produced some of the most creative and celebrated works on the Internet, videos that have been viewed by millions of people around the world.

We want to celebrate phenomenal video-makers and recognize the creative potential of the medium. So today we're collaborating with the Guggenheim Museum to discover the most creative video in the world, and showcase exceptional talent working in the ever-expanding realm of digital media: YouTube Play: A Biennial of Creative Video. This global online initiative is presented in collaboration with HP.

We're looking for animation, motion graphics, narrative, non-narrative, or documentary work, music videos and entirely new artforms -- creations that really challenge the world's perceptions of what's possible with video. We want to elevate the debate. This presentation, we hope, will garner some of the finest creative work from every corner of the globe, not only to showcase it on one of the biggest stages online, but also in one of the most iconic artistic venues in the world: the Guggenheim Museum in New York City, and throughout the Guggenheim network of museums in Bilbao, Venice and Berlin.

Participants must submit their videos to YouTube Play to enter. The deadline for submission is July 31, 2010, after which the Guggenheim will assemble a shortlist to be evaluated by an international jury of experts from the worlds of art, design, film and video. Up to 20 videos will be presented at the Guggenheim Museum in New York on October 21, with simultaneous presentations at the Guggenheim museums in Bilbao, Venice and Berlin. The presentations will also be viewable to on the YouTube Play brand channel at youtube.com/play.

As we did with the YouTube Symphony Orchestra, we hope to build an aspirational place for some of the world’s best artists to showcase their works and talents. For more information about how to enter, go to youtube.com/play.

Teams representing 32 nations have gathered in South Africa for the 2010 FIFA World Cup, the quadrennial football tournament celebrating the world’s most popular game, which begins Friday, June 11, and concludes in a month, with the championship match on Sunday, July 11.

This World Cup has special significance as it will be the first time the event has been held in Africa, where the game has been growing in leaps and bounds – besides host nation South Africa, Ghana, Ivory Coast, Nigeria, Cameroon and Algeria will be competing.

According to FIFA (Fédération Internationale de Football Association), the sport’s governing body, the World Cup is the most-widely viewed sporting event in the world, with fans everywhere following their teams with rapt attention.

On YouTube, there will be many ways to feel World Cup fever. Here are some channels to subscribe to:

- Coca-Cola is celebrating the tradition of the post-goal dance, giving people a chance to submit their original moves to the “Longest Celebration.” Submit here.

- Visa is creating an epic video of fans around the world screaming “GOOOAAALLL!” in the style of the iconic soccer announcer Andrés Cantor. Submit your video here.

- Last but certainly not least, Portugal striker extraordinaire (and international heartthrob) Christiano Ronaldo has joined the YouTube community and sends his regards to soccer fans:

Five years ago, Dutch professional footballer Edgar Davids gathered a talented group of Dutch street soccer players and travelled across Europe, the United States and Latin America to take on the best local teams, on their own streets. After numerous matches in five countries, Davids’ team emerged victorious and claimed the ‘Street Legends’ monicker.

This year Davids and his Street Legends are hitting the road again to see if they’re still are worthy of the title ... and this time you can watch their journey on YouTube.

The team started in Amsterdam before heading on to London and Paris. They passed through Senegal, Kenya, Ghana, heading for the bustling townships of Johannesburg and Cape Town in South Africa. Along the way, the best local street players from their respective countries attempted to de-throne Davids and The Street Legends, who were joined along the way by famous football faces like Ryan Babel, Michael Essien, and Marcel Desailly.

In Africa, The Street Legends and Edgar are also embarked on a personal voyage of discovery - understanding how street soccer influences people and how it thrives across Europe and Africa every day. Along the way, Edgar visited social grassroots projects across Africa that are providing healthcare, education and hope to thousands of men and women, boys and girls. Check out some amazing moments from their visits to Senegal and Kenya.
